The Chevy small-block is one of the most prolific engines ever manufactured, with over 90,000,000 units made. It was first produced in 1955 as a 265, and grew to 350 by 1967. The 350 proved to be the most popular variant with a 4.00 inch bore and 3.48 inch stroke, and has been offered in virtually every type of vehicle Chevrolet and GM has made, from trucks to sports cars and everything in between. It is one of the easiest engines to modify, with an almost endless variety of aftermarket parts available. The 350 was available as various models over the years, including the ZQ3, L46, LT-1, L48, L82, L81, L83, L98, LM1, L05, and L31.The Gen II small-block was introduced in the 1992 Corvette as the LT1 and was manufactured until 1997. It uses a different block and heads from the original small block design, and shares few parts with its predecessor. The LT4 was a short-lived high performance variant of the LT1.The Gen III LS series of engines debuted in the Corvette in 1997. The block and heads are aluminum for car versions, and cast iron for most trucks. The Gen IV small block came out in 2004. Both these engines have many versions, including the LS1, LS2, LS3, LS4, LS6, LS7, LS9, L76, and L98, some of which displace more than 350 cubic inches.Note that most shirts that have a small design on the front, also have a full-sized image on the back.
